GStreamer version macros.
Use the GST_VERSION_* macros e.g. when defining own plugins. The GStreamer runtime checks if these plugin and core version match and refuses to use a plugin compiled against a different version of GStreamer. You can also use the macros to keep the GStreamer version information in your application.
Use the gst-version function if you want to know which version of
GStreamer you are currently linked against.
The version macros get defined by including "gst/gst.h".
